I’m a creative, performance-driven Flutter developer with 4+ years of experience building and maintaining scalable cross-platform mobile applications. I build with Dart and Flutter, and I bring strong expertise in Firebase plus blockchain integration to deliver real product value. I’m especially proud of my focus on clean architecture, reliable state management, and intuitive UI/UX.

In my most recent role as a Blockchain & Flutter Developer, I led the development of “Blast Golf,” a golf training app used by thousands of active users. I integrated real-time sensor processing using Kotlin Multiplatform Mobile (KMM) via platform channels, achieving sub-100ms data transmission latency. I also built frame-accurate swing visualizations with Flutter’s CustomPainter, and created personalized feedback modules that increased user engagement by 35%.

From an engineering perspective, I consistently optimize both code and performance. I architected with BLoC and Clean Architecture principles, reducing code complexity by 40% and improving maintainability. I delivered measurable app improvements too—lazy loading, image caching, and tree shaking reduced app size by 25% and improved load times by 30%, while in-app purchase subscription flows using Firebase and Google Play Billing generated consistent revenue streams.

Before that, I developed and deployed smart contracts as a freelance Smart Contract Developer, working on DeFi applications and NFT marketplaces. I used Solidity with Hardhat, implemented security best practices (including reentrancy guards and CEI pattern), and integrated Chainlink oracles and IPFS for decentralized metadata. I also supported seamless blockchain interactions through Ethers.js/Web3.js, and earlier I gained solid enterprise web experience as an Angular Developer.
